Worked on the mermaid-js/mermaid repository to improve the accuracy and clarity of documentation related to Gantt diagram configuration. Focused on refining the gantt.md example by correcting the tickInterval format, ensuring it matched the required regular expression and schema documentation. This targeted bug fix involved updating Markdown documentation to remove ambiguity, specifically changing '1 week' to '1week' to prevent user misconfigurations. Emphasized disciplined change management by delivering a single, traceable commit that enhanced developer experience. Utilized skills in documentation and Markdown to align examples with technical requirements, ultimately reducing confusion and supporting more reliable usage of the Gantt feature.
